SPECIFICATION forming part of Letters Patent No. 587,276, datedJ'uly 27,1897.

Application filed March 15,1897.

To all whom, t may concern:

Be it known that I, VILLIAM H. BISBEE, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a new and usefulAdjustableSupport for 'Window-Shacles, of whichthe following is a specification.

My object is to provide a strong durable window-shade support adapted tobe detachably fastened to the upper sliding sash in such a manner thatthe shade will be raised and lowered by the sash and also in such amanner thatthe roller-bearings may be readily adj usted relative to thelength of the roller and the width of the shade or curtain attached tothe roller.

My invention consists in the extensible brackets and adjustableroller-bearings combined and applied and operated as hereinafter setforth, pointed out in my claim, and illustrated in the accompanyingdrawings, in which- Figure l is a face view of the top portion of-awindow and the top portionl of a sliding sash, showing my inventionapplied as required for practical use. Fig. 2 is a transverse sectionalview of the window and a top view of the .shade-support and the rollerin the adjustable roller-bearings. Fig. 3 is a perspective view showingone of my extensible brackets and adjustable roller-bearers combined andready to be detachably fastened to a window-sash by means of screws.Fig. 4: is a sectional view through the line y 'y of Fig. 3, showing awooden cross-piece adjustably connected with the extensible metalbracket. Fig. 5 is a sectional view through the line @c a: of Fig. 3,showing the two overlying parts of the extensible bracket slidinglyconnected.

The letter A designates a window-frame, and A2 a sliding sash iittedthereto.

B is one of the mating metal members ofthe extensible bracket. It has aright-angled and perforated integral extension B2, adapted to befastened to the top and corner portion of a sliding sash. It has anges cat its edges and a longitudinal slot c', through which a bolt CZ ispassed, to slidingly connect the mating member F therewith, that has acoinciding perforation through which the bolt Serial No. 627,504. (Nomodel.)

d is passed and secured by means of a nut in such a manner that the boltcan traverse the slot.

The member F has a slot c", and a bolt d' is extended therethrough andfastened to the part B, as shown in Fig. 3, so that the two overlyingparts B and F are slidingly connected. An enlargement 0" at the end ofthe slot in the part B allows a hook-shaped projection 0 on the end ofthe part F to pass through and to serve as a bearing for the slidingpart F, as required to extend it or adjust it relative to the part Bwhen fixed to a sliding sash A2.

F2 is a lateral right-angled extension at thev free end of the part F,adapted for detachably and slidingly connecting a wooden crosspiece H.It has a slot t', through which a screw t" is passed into the woodencross-piece H in such a manner that the screw can traverse the slot whenthe part F is moved longitudinally.

t'" is a stud integral with the top edge and end portion of the part F,that serves as a bearing in support-ing and guiding the sliding movementof the cross-piece H.

J is an angular met-al sleeve fitted and fixed to the end ofthecross-piece H, and J2 is an elbow-shaped metal roller-bearer fittedin the said sleeve. It has a slot J 3, 4througji which a screw 7o ispassed and fastened into the wooden cross-piece H in such a manner thatthe screw lo will extend through the slot J 3 and allow theroller-bearer J2 to be adjusted relative to the said bar and the lengthof aroller L and the width of a shade or curtain fixed to the roller.

It is obvious that my extensible bracket and adjustable roller-bearermust be furnished in pairsrights and lefts.

I claim as my invention- The extensible bracket comprising the part ormember B having a right-angled perforated extension B2, flanges at itsedges and a longitudina-l slot having an enlargement at one end, amating member F having alongitudi- A IOO screw, all arranged andcombined to operate in to said right-angled extension and sldngly thenmnner set forth for the purposes stated.

connected therewith by means of a screw ex` tended throuvh said slot, a,sleeve J tted to l Y v the end 0i' ttlqe cross-piece, and an elboW-XVILLIAM H' LISBEE' 5,s11aped roller-bearer J 2 fitted in said sleevelVitnesses:
